Your flexible steering shaft coupling is being pulled apart! Not a good situation from a safety standpoint! The rubber disc in the flexible coupling should be flat as it connects to the steering column flange. Also the stop pins extending from the coupling itself should be central in the column flange slots and extending up through the slot by 1/4 inch or so.
Here are a couple possible causes of this problem.
The steering gear is bolted to the engine cradle and there is no adjustment possible in this gear to frame attachment. However, is it possible that the cradle (front end) was damaged in an accident?
If the gear is correctly located, then the problem has to be in the steering column itself or in the mounting of the steering column to the body.
I see that you have a standard (non-adjustable) steering column. This scan is of a 1969 F-Car tilt column lower end. You will note that there is a 2.00 dimension from the lower face of the steering column flange back to the face of the lower bearing retainer. Although your standard column parts may look a little different, that 2.00 dimension should still be valid. The steering column shaft is designed to telescope back into the steering column in the case of a severe frontal collision. (It is also possible to telescope the steering shaft back into the column by prying on the flex coupling or by careless handling of the column when it is out of the car.)
So if you can measure that 2.00 distance on your column then that will answer the question as to the steering shaft being collapsed into the column. BTW, the steering shaft always seems to telescope back into the column a lot easier than it comes back out. If needed, you want to pull it out to that 2.00 dimension with a steady pull -- not hammering on the flange. You can damage the steering column bearings by hammering.
If the gear is correct and the steering column shaft 2.00 dimension is correct, then the problem must be in the steering column mounting. There is a slight amount of adjustment possible in the two vertical attachment fasteners as well as the clamping of the column jacket to the vehicle body (down by your feet.) You will want to try and position the steering column down into the body further than it is currently. You must also make sure that the column mounting keeps the column aligned to the steering gear. When you are done installing the column; the rubber coupling disc must be flat and the stop pins central in the column flange slots. Rotate your steering wheel one quarter turn and recheck that the stop pins are still central.
